Application filed June 20,

To all whom it may concern Be it known that 1, PAUL O. H'OHBEBG, a

subject of Germany, and resident of: 153 Prospect Ave, Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Can general and particularly to the kindwhereby the cover of a can is opened at the edge thereof.

The primary object of my invention is to provide a device of this kind by means of which a can may beopened without necessitating the device being centered.

Another object of my invention is to pro videin connectionwith sucha device, means whereby the cuttingmember is automatically guided at the edge or" the can top, no matter of what shape the topmay be.

Another object of my invention is to provide in connection with such a device, sliding and self-adjusting means carrying the cutting blade which permits the unrestricted operation ot the blade atthe inner edge of cal can, showing my device inoperation. 35

Fig. 2 represents my device designed for left handed operators.

Fig. 3 is a detail view of my cutting device.

Fig. 4: is a modified form thereof.

Fig. 5 is a top view of my device in modi fied form, shown in operation upon a square can.

I am aware of the existence of numerous devices of similar deslgn, but of considerably different construction. As a rule, the

guiding mechanisms of can openers now in use are not only slidably associated with the handle, but also prevented from any swiveling or plvoting movement, whlch movement becomes necessary when it is desired to cut the can exactly at the edge without requiring that the fulcrum of op 1921. Serial no. cranes.

represents the handle of my device, in which isfirmlyheld a flattenedbar 11, having at its free end an angularly shaped point 12 which is adapted to engage the can cover proper 13 at any desired point.

Slidabl'y and pivotably mounted upon the flattened bar 11 is a carriage 14 which em braces rod 11 at three of its faces.

The open portion of the carriage extends outward-1y at the upper face as indicated. at 1.5

for receiving a rivet 16, which passes through the lower extension 17 of the can riage. 1

Between the upper and lower part ofthe carriage a small roller indicated at 18 is preferably provided for spacing the carriage at its open end. The lower portion 17 extends into an arm 19 or 19 (Fig. l) which is turned downward as shown and is adapted to guide the carriage at the outsideof the 1 can top. 1 i r The cutting blade of my device may *form 1 an integral part of the carriage as shown in Figs. 2 and 8 at 20, or may be set into the carriage material as. indicated at 20' in r ig. 4:.

The blade is ot'set relative to arm 19 or 19 so that when the carriage is placed upon the can, the blade engagesthe can edge at its inner surface, while the arm glides at its outer face.

Rivet 16 and roller 18 serve two purposes. Firstly, they provide a thrust point for the bar 11 during the cutting operation, and secondly, they facilitate the rolling or self-ad justment of the carriage relative to the bar when thecarriage follows the edge of the can.

While I have shown in Figs. 1, 2, 3, and 1, a particular design of my carriage, it might be advantageous in order to provide freer movements or the carriage relative to bar 11 and the can edge, to cut out the carriage portion facing pin 12, as indicated at 21. It will also be seen in Fig. 5 that sufficient free space 22 is left between the closed part 23 of the carriage and rod 11.

i The operation of my device is similar to that of like devices with the difierence that it becomes unnecessary to engage the center of the can by pin 12. After having pierced the can by pin 12 at any pointof the can top, the blade 20 is set at the inner face of the can edge, while 19 abuts with the outer edge of the can. Now the handle is turned of the blade is square as at in device WOI'kS in a similar manner as would a lathe tool. Due to the construction of the can riage, it is pei'niittodto slide or glide upon ll vhile following; the outer edge of the can.

.1 he cut made la "my tool. is at the extreme inner edge the'can cover, thus the entire .cmitents of the can may le readlly emptied heretofore.

"without necessitating the forcible removal oi; the contents which is usually due to the incomplete outta of the cover by tools used apened With my device- While I have shown a particular construction of my invention, be it understood that its Working method is the main object of my invention, and I do not WlSl1;ilO restrict myself to the particular design shown, and I therefore reserve for myself the right to ii'laliQ suzhh changes and improvements with the scope of H13" invention to meet various 1 ondi to which my (lev e may he put. li anng thus described invention l; claini:
